一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Ripasudil (K-115) 是一种新型的Rho激酶抑制剂,具有强效的降低眼压的效果。Rho激酶可被小GTP结合蛋白Rho激活。越来越多的证据表明,Rho/Rho激酶通路参与各种细胞功能,例如血管平滑肌细胞(VSMC)的收缩、肌动蛋白细胞骨架形成、细胞粘附和运动性、细胞分裂以及基因表达。这些功能障碍可能涉及诸如冠状动脉痉挛等心血管疾病的发病机理[1]。
在体实验:在视神经损伤(NC)的C57BL/6小鼠模型中,在NC后,口服K-115 (1 mg/kg/d) 增加了RGCs 34 ± 3%的存活率[2]。
临床试验:在I期临床试验中,滴注后2小时内进行测试,健康男性成年志愿者中,0.05%、0.1%、0.2%、0.4%和0.8%浓度的K-115使眼内压(IOP)从-1.6 mm汞柱下降至-3.4、-2.2、-2.6、-4.0和-4.3mm汞柱[3]。在2期原发性开角型青光眼或高眼压症的随机临床研究中,每日两次K-115,持续8周,K-115剂量依赖性地降低了眼压水平[4]。
